摘要:
A pipetting device includes first and second bodies, through which a plurality of pipettes extend. The surface of one of the bodies is free to move relative to the surface of the other body. Relative motion between the two bodies causes an inter-pipette distance exhibited by the pipetting device to vary.
摘要:
A composite sealed vessel is provided. The vessel includes a non-metallic, generally cylindrical inner containment piece, a non-metallic, generally cylindrical outer containment piece disposed around the inner containment piece. A pair of non-metallic flanges are disposed at ends of the inner and outer containment pieces to form a closed structure defining a cavity therein. The vessel also includes a metallic external lining disposed over the closed structure to form a leak-tight pressure boundary.
摘要:
An imaging system including at least one pole piece is described. The at least one pole piece includes at least two grain-oriented sheets that are stacked together, where a direction of easy magnetization of a first of the at least two grain-oriented sheets is different than a direction of easy magnetization of a second of the at least two grain-oriented sheets.

Embodiments of systems and methods for implementing multi-channel tuners are generally described herein. Other embodiments may be described and claimed.
摘要:
A composition of matter is provided comprising a metal oxide or metalloid oxide substrate, ⊕, having a surface that is covalently bonded to a silyl moiety according to Formula: —Si(R1)n(X)m(Y)q wherein R1, X, m, n, Y and q are defined herein.
摘要:
A transistor circuit including a capacitor charging circuit and an actuator such as an electric motor provides a two part cyclic timing circuit, one part being one complete revolution of the motor and the other part being the charging time of the capacitor. The entire device is designed to run for an extended period on two dry cells. Practically no current is drawn while the motor is at rest contributing to a long battery life.
